PROCESS FOR TREATING A GAS OIL

摘要

The present invention relates to a process for hydrodesulphurising a gas oil wherein a sulphur level of less than 50 ppm is obtained, said process comprising a) contacting a gas oil with hydrogen in the presence of a hydrodesulphurisation catalyst, and b) adjusting the temperature and pressure of hydrodesulphurisation so the temperature - pressure relationship lies on or between the curves T = 211.15 P<0.1363> and T = 243.83 P<0.1232>, for all values of P >/= 0 where T = temperature in DEG C, and P = pressure in bar a.
